Description

Synchronized hinge device pivot

The present invention relates to a pivot for a synchronizing hinge device.

With the development of electronic devices, there are a variety of panel products that require a hinge device to enable folding or relative 360° tilting of electronic products that are constructed of two hinges; fully open and 0° at 360° Fully closed, and some intermediate angles remain open, etc., can be smoothly operated or positioned. Therefore, a number of synchronous or non-synchronous mechanisms have been developed to supply the hinge device. One of the methods of synchronous opening and closing is to use a plurality of gears to drive each other to achieve the simultaneous opening and closing of the two hinges.

At the same time, in order to be convenient to carry around, the existing folding electronic devices such as notebook computers are designed to be lighter, thinner and shorter, but existing electronic devices such as the two separate pivots of the dual-axis pivot can be synchronized. Generally, a gear transmission mechanism is adopted. A gear transmission mechanism applied to such a biaxial pivot is generally provided with a driving gear at two pivot ends, and transmits power through an intermediate gear set, but using a conventional gear mechanism. In the case where the Orthodontic shape is used as the transmission, although the gear thickness or the tooth surface length allows a better narrowing condition between the two meshing spurs, and the axial meshing position between the teeth and the teeth provides a smaller Binding, but still because of the meshing between the two teeth, it is necessary to retain sufficient backlash to facilitate smooth operation, but it is The disadvantage of large transmission error between transmissions; this not only directly affects the stability of the synchronous transmission between the two transmission gears, but also directly provides the shortenable condition of the center distance between the two parallel shafts, so that the volume and thickness of the entire two-axis pivot The degree of reduction can be greatly limited, which is obviously not conducive to the thin and light design requirements of the entire electronic device.

In addition, in order to enable the simultaneous rotation of the double shafts of such a double-shaft co-rotating pivot, two opposite lead screws disposed on the two rotating shafts are used, and a sliding or rolling member is assembled between the two opposite lead screws. As a synchronous braking element, it is also a feasible way. However, since the slider between the two opposing lead screws is in the process of reciprocating displacement, the synchronous interlocking control is mainly performed along the spiral grooves of the lead screw provided on the two rotating shafts, and the sliding member or the rolling member is to be engaged on the one hand. The spiral groove of the lead screw is used for reciprocating displacement, and on the other hand, the movable margin space is assembled, thereby making it possible to create a gap between the two opposing lead screws and the slider. This gap in the synchronizing mechanism may cause sloshing and displacement instability, and the electronic hinge device may affect the stability of the positioning function and the use state under various use angles. At the same time, it is more difficult to miniaturize the entire two-axis torque pivot because the two opposite lead screws of the longer actuation stroke must be used.

In addition, in WO2005/101963, a technical structure using a plurality of conical gears (helical gears) or bevel gears to transmit power and synchronously rotate the double shafts is disclosed, and a spur gear is provided for the application of the conical gears. The characteristics of stability. However, as is known to those skilled in the art, with bevel gear transmission, the bevel gear must have sufficient Cone Distance or Face Distance, and the two-phase meshing gears must be perfectly aligned. , axial direction during assembly The accuracy is high, in order to provide a good and smooth meshing transmission effect; therefore, the above embodiment has a plurality of bevel gear transmission structures on the double shaft, and if the conical gear is transmitted as the middle of the two parallel shafts, Between the shaft side and the shaft side, the pitch of the double shaft cannot be reduced as much as possible because of the necessity of the length of the cone or the length of the ruler. Conversely, if the cone gear is transmitted as the middle, The arrangement is at the ends of the two parallel shafts, but it will increase the occupation of the space at the ends of the two parallel shafts. Therefore, it reflects that the entire transmission or structure needs to occupy a large space or volume. In particular, the transmission device is applied to a notebook computer or a small electronic device, and cannot meet the requirements of a lightweight and thin design; this situation is not what we would expect.

Therefore, from the above discussion, we can find that whether it is driven by a simple spur gear set or a sliding member or a rolling member between two parallel shafts, although there is a better narrowing condition in the use space, it will be due to the backlash. Or the existence of the slider gap, so that the synchronization stability between the two parallel shafts is adversely affected; furthermore, if the conical (oblique) gear is used as the transmission element, although better contact transmission stability can be provided, However, it is more difficult to overcome the lack of space or volume. And as a subject to be improved.

Accordingly, it is a primary object of the present invention to provide a pivoting device for a synchronizing hinge transmission that provides a transmission that can reduce the distance between the two shafts and the high contact ratio, thereby making the application electronically lightweight and Pass the stable design features. The pivot of the synchronous hinge device includes an actuator disposed on a first shaft; And a reactor disposed on a second shaft, a coupler having a relationship between the two ends and the actuator and the reactor, respectively, forming a relationship between the spur gear and the umbrella (oblique) gear, thereby The Orthogonal and Helical (umbrella) teeth can be combined to balance the shortcomings of each other, providing a stable and compact synchronous transmission. When the first shaft drives the actuator to rotate, the actuator drives the linkage to rotate, forcing the reactor to rotate in the direction of the movement of the opposite actuator, so that the first shaft and the second shaft function as synchronous rotation patterns.

According to the pivoting device of the hinge synchronizing device of the present invention, the synchronizing transmission is disposed on the first shaft and the second shaft between the main fixing plate and the sub fixing plate, and between the main fixing plate and the sub fixing plate The joint is also pivotally connected. Further, a groove may be provided at a portion where the main fixing plate and the sub-fixing plate are pivotally connected to the interlocking device to reduce friction and provide lubricating oil or the like to improve and maintain the smoothness and smoothness of the movement of the connecting body.
